Lenovo TB3-710F and Android 6 or 7 - Android Q&A, Help & Troubleshooting

Lenovo TB3-710F and Android 6 or 7 - Android Q&A, Help & Troubleshooting

Hi all
I am trying to upgrade a Lenovo Tab 3 (TB3-710F) 7" tablet because Android 5 is the latest official version. Ideally, 7 is better, but I will be happy with 6. I have downloaded SP Flash Tool and TWRP 3.0.2, and that is installed correctly and all working. Now the actual ROM is the problem. I have downloaded Resurrection Remix, LineageOS 13, Viper and Dot, and it would appear most of them have the same problem. When I try to install the zip file, I get told that it's unable to unmount or mount /system and it crashes out with signal 11. I have tried to wipe and reformat the system folder, again being told it's unable to unmount /system, and have changed the file system from NTFS or exFAT and back to Ext4, but to no avail. I suspect until I can format the system folder correctly, it won't install, but for the sake of me, I can't. Has anyone got any advice?

A custom rom would be great for the tb3-710f.
I have just done a factory reset and most Google apps won't run because play services can't update.

bump

I've just upgraded to 5.1.1 on a TB3-710F using an old CyanogenMod cm-12 custom rom so that I can use Google's FamilyLink, works well.
Do you have a link to the LineageOS 13 rom?
I also had a similar error installing the cm-12 rom but that was because I'd missed wiping /data in TWRP first before attempting to install the rom.

YESS>>> We need lineage os for TB 3-710f.. I too use cm12
SOOOO.... Anyone??

I too have CM-12 on my Lenovo. so anywhere have a link to download any custom ROM but not CM-12.

let me explain, firstly

because all of those ROMs are not compatible with your device. that is why it won't flash. If you force it to install that specific ROM, it might end up in a boot loop. You must have not deleted all your files. :c

You did not upgrade though. The tablet is literally on 5.1.1 so maybe you did this because you hate the lag of its own UI provided by Lenovo. Well that is a good choice. Although, it does not make any difference between the apps that you can run and can't run because it is still in the same version (Android 5.1.1).
To be honest, even if you try to find a Lineage OS ROM, it is useless because it is not on the list of supported devices. Almost all custom ROMs do not have this tablet on their list (I hope they added and modify some **** because we really need it :c). For now, the only custom ROM that I know this tablet can have is Cyanogenmod 12. It is your own choice if you want to install the buggy ones. The buggy ones are, Lineage OS and Flyme OS.

Lineage and Flyme doesn't install for me.
Did a clean install with the stock TB3-710F_S000028_170316_ROW. Then format. Then tried to install the two ROM's.
I noticed the install log shows the variant 710X. My tablet is a 710F
What am I doing wrong?

Enjoy ¡¡¡

yes, it's a good one. just installed no problems so far.
I had a problem with previous stock versions that 4G speed had some hickups....when I was downloading (for example from google store) it paused for 30 seconds..sometimes longer.
tried SIM in slot 2 and vice versa..but problem remains.
now it goes smoothly without pauses (so far)
also had the CM13 which is almost the best, apart from the sound bug...definitely one I want on this phone for a long time..if sound thingy is fixed.
thanks!

Recommendation Do Not Use India version
This version apparently has data encryption enabled and will not show a viable data partition. This will cause TWRP to fail and subsequent attempts at root or installation of other roms.

Hmm..Ok! phone is encrypted indeed..do you know if there's as a way to decrypt or turn it off.?twrp is asking for a password when going onto recovery now...in previous roms the encrypt option was not greyed out.
or is only way to get in twrp and wipe everything.

Thanks !

What is the way around the issue of encryption? So we can never install TWRP ever?

Under TWRP data it´s encrypted. But under Windows not. Copy to your computer all files that you need save (photos, music, etc.), and then format data in TWRP.

Under windows DATA partition works properly, copy all your files (photos, music, etc.) into computer and then enter TWRP and format DATA.
This ROM it´s better that anyone, I think that worth trying. It´s awesome.

You did not understand my question properly.
Right now, there is absolutely NO way to install TWRP on Indian X821 model. I cannot format DATA without installing TWRP.
All the TWRPs available on this forum give a BLOD (Blue Led of Death) The screen remains blank but powered on. The Blue LED light remains. There is another guy who is having the same problem and he has created a separate topic for it.
We can restart the phone normally but the installed TWRP gets overwritten with stock recovery.

atm here is no solution for your device, you need to wait until a developer create a TWRP compatible for your device.

What I did was to go into settings -> fingerprint -> -> other security options -> trusted credentials and disabled the credentials. You have to do this one by one as the clear all option is grayed out. From there I went into and fast boot and flashed TWRP recovery. I rebooted immediately to RECOVERY wiped everything on internal storage. I then transfered a ROM to storage and flashed normally. All is working again and TWRP and root are functioning.

WTF, ok it is a security related issue?

I flashed old 14S Chinese ROM and then flashed recovery. My phone shows X820 now. I guess X820 and X821 may be just the same. It's the Chinese Roms show X820 and Indian Rom shows X821.
BTW I am on TeamSpain's CM Rom. Working good except charging.
If I used my Aukey QC 3.0 charger, the LED flashed like crazy and Ampere current measuring App showed 4680 mAh charging current and was climbing. (QC 3.0 shouldn't exceed 3000 mAh) So I immediately disconected it. Gave me a scare for a moment. Normal charging is slow but no LED blinking and feels safer.

Not a security. Just a way for Indian Dev's to prevent users from messing with their OS and to keep users on 100% stock.

So can someone clarify if there's a way to clean install this ROM on a Chinese version of the phone and have a) TWRP b) ROOT working or is that impossible for now?

Exactly the same way as you install any other ROM. I have a Chinese phone and installed this ROM and uninstalled it because of its encrypted. Yes, the le-bloat is gone, but you will be unable to install TWRP or root because of the encryption.

GApps error after installing custom ROM

So I have got this Samsung Galaxy Tab 2 3G 10.1" that has been lying in a cupboard for a around a year, mainly because I've been busy Now there's a family member of mine who would really need a tablet so I thought this one would be perfect for her!
From thinking I went on to doing and started with getting rid of the stock software and installing some nice custom ROM.
As I found out i couldn't use USB (probably busted data-cable), I rooted the tab using KingRoot and went on installing CWM recovery. Afterwards long story short: I've tried both CWM and TWRP, different ROM and android versions (Lineage, CM, Slim etc.) and different GApps packages from different developers but the problem still seems to come up :crying:
The problem itself is that when I've installed any of the above mentioned ROMs, all the GApps seem to not have been installed correctly (even though the installation process in recovery went smoothly) and basically none of them works (notifications saying that any GApp has stopped keep on coming up and I can't find any Google app in the menu except something things like "com.google.android..." or "com.android.vending...") otherwise everything seems perfectly fine.
Maybe there are others here experiencing the same issue or there's someone who knows how to fix this here, any help will be very appreciated :good:

Hello,
First, have you checked that the ROM you flashed was fully compatible with your device? Yes, this is obvious, but I have to ask.
Second, I'm not a ROM flashing via custom recovery fan... The best way to efficiently flash a ROM in my opinion is Odin-Download mode but whatever (your USB port is screwed, so pfu.)
Redownloading apps doesn't work for you? (updating the apk may fix that!)

Yes, I do have used ROMs compatible with my device as they've all are made for espresso3g (which is my device).
I know it's not really the best way but I'll keep on trying with custom recovery for some more time and then perhaps try buying a new cable, and see if that works.
Tried installing Google Play Store from APK both on a clean ROM without GApps and with, but it still doesn't run and keeps on saying that either Google Play Store or "com.google.process.gapps" has stopped.

Alright...
I'm out of idea x/

Hello...!
You could try the following....
1. make absolutely sure you are using the correct version of gapps for the custom rom you are currently using. If your custom rom is on android 6, you need gapps for android 6 for example.
2. after flashing gapps wipe cache/dalvik and make a factory reset BEFORE exiting twrp. You will lose personal data but since you are preparing to give the device to somebody else that should not be much of a concern.
Let me know if it helps, if it does not, I might be able to try and provide additional suggestions.
Good luck!

Hi and thanks for your reply!
1. The ROMs I've been trying to install are all android 6.0.1 and I've been trying with different OpenGApps packages for the 6.0 version which should work (except CM 12 which is android 5.1 with which I've tried OpenGApps and A-Gapps for Android 5.1).
2. Tried that with 3 different ROMs today and the results are following: Slimrom gets stuck in setupwizard which doesn't start, CM 12 starts but the same error as first seems to appear (I get notifications about GApps which stop working) and Lineage bootloops the lineage start screen.

Ok...
This is what I would do if it was my device and I was facing what you are describing. It might take some time and a little patience to do everything described here, but it might also work.
1. Usin Odin, flash latest available official rom for the device. Let it boot and complete setup.
2. Use odin and use CF autoroot to root. Again boot and complete setup.
3. Flash Twrp. Enter Twrp and flash latest flashable supersu.zip. At this time I believe is version 2.82. Again boot and let it reach your welcome screen.
4. Enter Twrp. Enter advanced wipe. Wipe everything except external SD and usb at least 3 times. Do not exit twrp.
5. Install you rom. Do not exit Twrp.
6. After installing your rom, Twrp will ask you if you want to wipe cache/dalvik. "Yes" but DO NOT reboot.
7. Install correct version of gapps for your custom rom (correct both android version and architecture version). Again twrp will ask you to wipe cache/dalvik. "Yes" and this time reboot.
See what happens. If it gets stuck, try entering twrp again and do a factory reset only, only once and reboot again.
If that fails again... I will at a loss here myself too...
I did a quick search here on xda on P5100, I am providing some links that you can take a look at. You probably already searched yourself but you never know...

If nothing else helps, perhaps the best way to go around this would be to find a custom rom with at least some google apps pre-installed, in order to save you the trouble you are currently facing.

Hey, just try uninstalling Google play services and install them again. I faced the same issue and now it's all working on my Samsung Galaxy Core 2

Bootloop/no complete shutdown on H850 with latest lineage-17.1

Luckily I'm using now my S5 Galaxy (G900F) with lineage 16.0 cause my LG G5 (H850) is driving me crazy.
What I did so far:
+Bootloader unlock
+Installed TWRP 3.2.3-2 than an update to 3.4.0
+flashed no-verity-opt-encrypt-6.1
+wipe format data and advanced wipe with cache + system
+flashed latest official lineage-17.1-20200705-nightly-h850-signed
The big problem is when I try to shutdown my smartphone its vibrating wild and instead of doing the shutdown its lunching a reboot. Only way to completly shut it down is to remove the battery. Did I miss anything?
Official instructions are not very usefull cause the sideload method didn't work either. I thought because its classified as official that 17.1 is running stable on H850 If I knew that before I would buy a different smartphone cause Samsung was way more custom rom friendly (had no issues with my S3 LTE and now with my S5). Since 2 weekends I try to fix this issue and read xda postings + user feedback on reddit but sadly haven't found any solution till now.

+flashed no-verity-opt-encrypt-6.1
+wipe format data and advanced wipe with cache + system

Any update?
If coming from stock rom I think you need to format data during the wipe process. Also, I recall reading in order to get 17 working you may need to be coming from Lineage 15 or 16, although I wouldn't swear to it (not currently on lineage). Did you flash no-verity last? Even though you seem to dislike it, I'd recommend troubleshooting within the Lineage 17.1 post.

Thanks for trying to help me out. Sadly I hadn't any luck yet - I will test my micro sd card cause I've read in a different posting that damaged micro sd cards can also cause bootloops.
The whole process to install 17.1 from stock rom seems not very well documented - this is the biggest issue I'm facing at the moment actual it's more like a try and error thing which realy sucks. Do you know if these bootloops are maybe logged in a file somewhere? I guess in this forum are enough tech people who can deal with such log files and can tell me whats going wrong.
I can't post my problems somewhere else (restricted to Q&A part of the forum) cause I'm a newcomer so forum system is giving me some restrictions.

I had bootloop problem with lineage-17.1-20200712-nightly-h850-signed.zip on my H850 although no problems with the previous build (20200705 ) installing today.
Following : wiki.lineageos.org/devices/h850/install/ was clear and straight forward for me.
- unlock bootloader
- install TWRP
- sideload Lineage + open Google apps
cheers

I bought a fresh LG data cable and setup a complete fresh Linux Mint installation on my notebook. In TWRP I followed your tutorial (wiki.lineageos.org/devices/h850) and did fullwipe followed the tutorial here to install adb tools on Linux and was able to sideload "lineage-17.1-20200719-nightly-h850-signed.zip". Sideload succeeded (confirmed on linux terminal and TWRP). After sideload I did reboot and I got configuration menu from lineage. After skipping most of the config steps I did reboot and AGAIN BOOOOOOTLOOOOOP no complete shutdown.

can be closed solution was first flashing Android 8 stock rom with uppercut (H85030f_00_OPEN_EU_OP_1122.kdz) than flashing custom rom based on Android 9 (lineage-16.0-20200811-X86CPU-h850 - thank you to the author) and than I was able to flash official lineage 17.1 than bootloop was suddenly fixed. Each time after flashing I just did normal wipe (confirming with yes).
official tutorial completly sucks:
https://wiki.lineageos.org/devices/h850/install
-> sideload is not necessary and when you come from older Android Version you have to flash Lineage 16 before (no evidence and no image in download section).

Phone runs very hot in official lineage os 17.1

So, I install lineage os every one's and a while to test it and see if it is ok for me, I always revert to stock but that's not the point, one problem that I have is that the phone gets VERY HOT. One day I installed lineage and when I finished the setup process, the phone was so hot I couldn't hold it comfortably, while when I finish the setup on the stock rom the phone is just warm. Is there any way to make the phone run cooler? Is the phone getting hot because the software is too much for the processor? . I haven't installed lineage os for about two months now so I may try it again at some point. Is anyone else having the same problem?

No that's not normal, it's not supposed to heat up much.
Maybe you you didnt flash it properly, it's recommended to install it like this.

Also check before flashing if your camera works on the stock lg rom,
If it doesnt you have to downgrade to stock marshmellow, and then upgrade back to oreo to fix it.

Thanks for answering,
This is how I install it. The camera on stock oreo is working normally so I don't need to install stock Marshmallow. So, I firstly unlock the bootloader and then install lineage os 15.1 with no gapps. After that I upgrade to lineage os 16.1 again with no gapps. Now I uninstall lineage 16.1 and I am doing a clean install of official lineage os 17.1 WITH gapps. The reason I do this is because if I install lineage 17.1 instantly the cameras and sensors don't work. Unfortunately I don't remember the temperatures that I got but I remember that one day I woke up with 20 C and after 15 minutes of some web browsing and social media it went up to 40 C (there's a slight chance that I'm wrong since I don't remember the exact temperatures as I said)

Strange i didn't have those problems when flashing properly,
Do you also use nano/pico opengapps?
You could also give crDroid Android 5.12, a try maybe that will work well, but it's android 9 instead of 10.
I think you need to flash it in the same way as lineage.

I originally used nano opengapps but I started using stock because I use most of the gapps anyway but I will try crdroid 5.12 at some point to see what happens.

[ROM][UNOFFICIAL] [SM-T290] LineageOS 18.0 [BETA][21.02.2022]

Build in the works. Going to release the BETA as soon as I can do testing on my own device before release.
IMO this is a necessity as there are literally no good roms for this right now. I tried the port of the Nexus stock CR rom and it was not great. Playstore was unusable due to an issue were the app thinks the system is out of storage space, even though it is almost empty. Chrome crashes instantly, the search on the page home screen flickers up/down without control.
I am a far bigger fan of LineageOS thus why I am working on this build.
More to come.

As a follow up to my original post I wanted to mention that for anyone who wants a new ROM on their SM-T290 until this is finished development, use the Nexus Rom by Magendanz. I was able to do a fresh stock firmware install and retry the rom and my opinion has changed. I have noticed that these Tab A 8.0 tablets have been used a lot for like Uber/Door Dash and other POS terminals. I am pretty sure a lot of them have modified or customized firmware for these reasons and when I mine second hand it was from a pizza store. I think that messed up the upgrade.
Overall Magendanz did a great job, when you install it properly. I have zero issues with functionality now, TWRP recovery set up, as well as Magisk installed and everything is running extremely well.
As far as instruction on how to install. Take a look at some of the comments further down on the Nexus thread. That is what I did this time around and it worked perfectly. Last thing I did was copy Magisk.Apk to my SD, change extension from .APK to .ZIP, then boot into TWRP and install that ZIP.
Going to update progression on a monthly basis as far as the LineageOS 18.0 build

Do you have a github with your source code and manifest? I just got this tablet (used) yesterday and I would like to see if I can help. I have built LineageOS roms for a number of older Samsung Tab A devices, but will have to do some research on the "new to me" T290. Thanks.

Just got this tablet, how's the beta coming along? And what can I do to help?

Thank you my guy I had lost all hope for custom roms on this tablet. It's quite relieving to know that I'm not alone.

Also, has anyone experienced severe lag on one ui 3 while doing basic tasks? The thing literally gets 5 fps while watching youtube and surfing the web but it plays 3d games at 20 fps on low settings. wtf

Hey Guys,
I didnt end up building a custom rom, because I was able to get the GSI version of Lineage 19 working fairly easily. Just use the correct image and flash the same as the Nexus post. Android 12 with Lineage 19 so i felt it wasnt worth it as everything works. I had trouble at first with a boot loop but that was because I had installed Magisk BEFORE the GSI rom and not AFTER. So dont make my mistake.
As per the Nexus Post;
Unlock Bootloader
flash TWRP
Wipe data
Install Andy Yan's Lineage OS 19 GSI
Andy Yan's personal builds // GSI - Browse /lineage-19.x at SourceForge.net
sourceforge.net
Install Magisk
Reboot
Cheers!

Good advice But which of Andy's GSIs did you use exactly ?

Thanks so much dude

The GSI is a .img.xz will it work or does it need to be .gsi

You download the .img.xz file and unzip it.
Inside this will be the .img file
This is what you need to flash (.img)

Sorry
Use this one
lineage-19.0-20220211-UNOFFICIAL-treble_arm64_bgS.img.xz
It has Gapps built in as well as super user through SSH, dont install Magisk as it will error that there is already SU tool installed.

@SniperFox22 , did you make a github for the code or didn't even start since you are happy with GSI?

My OS didn't have an option to unzip it at first glance. I haven't been able to install gapps so I'm gonna try that gsi. Also, am I supposed to wipe internal storage before flashing or not?

I got it working but games just crash which is worse than before

Came across this while trying to root my sm-t290. Just want to add that Andy Yan has upgraded to a 19.1 version that appears to work just fine. Flashed to system partition using twrp after I had flashed the Nexus rom. Wifi works, sound works, sd card, bluetooth keyboard works just fine.

Link to it???

I like the link above because it has all the versions but lineage-19.1-20220320-UNOFFICIAL-arm64_bgS.img.xz is the one that I used. The page has the naming convention. Ill mention that even though it says that it's supposed to be rooted, I couldn't get it to work right. The nexus rom had an option in the 'phh treble' menu to activate root and this lineage image should also but the option wasn't there. It kept saying the supersu binary was busy but that was after I flashed a supersu.zip(it may have worked before then i don't know). I played with it a little bit but ended up just flashing back to the Nexus rom.

Hey guys!
Installed "lineage-19.1-20220320-UNOFFICIAL-arm64_bgS.img"
Everything starts up, but something is weird with my installation and my storage, it freezes when i go into storage and i cant download anything without apps start to crash.
Im not sure if i flashed it correctly, i did a wipe in TWRP before installation.
Really hope i can get this to work since it waaaaay faster then the bloat samsung ships
Edit:
Tried flashing another rom (nexus) and had the same issue!
trying to reflash and wipe everything except internal storage.
Where should i flash image? i get: "select partition to flash image", never seen that before (might be because you flash img and not zip)
